Patented Apr. 1, 1919.

Application filed March 27, 1918. Serial No. 225,033;

To all whom it may concern:

Be it known that I, GEORGE B; Von BODEN,

a citizen of the United States, residing atmay be employed in conjunction with steam as a fuel in a burner, which is especially adapted for use in fire boxes of the type employed on locomotives.

whereby direct and indirect heatmay be applied to'the oil in such a manner as to prepare the oil for use in the burner.

It also includes details of construction which will be more fully explained by reference to the accompanying drawing, in

which is located an oil burner 2, of any suit.

able character,adapted to discharge a spray of oil into the fire-box where it is ignited. 3 is an oil tank which is located upon the tender 4 which occupies the usual position with relation to the engine boiler and the box.

In the bottom of the oil tank is a heating box 3 and arranged within this box is a heating coil 5, through which steam may pass to heat the oil and render it suitable for use in the burner. A valve 6 may be opened by means of a bell-crank or suitable lever 7 and a connecting rod 8 withinreach of the fireman who may thus control the supply of oil from the tank. 9 is a flexible hose or conductor, through which the oil may pass from the tank to av pipe 10 leading to the burner in the fire-box, and 111s a superheater inclosing the pipe 10. A fountain or' manifold 12 is supplied with steam from the boiler and pipes lead from this fountain and deliver steam to the tank heater, the super heater, and to the burner.

The pipe marked a leads to the burner and blow back, I) carries steam to the steam passage of the burner, c carries steam to the It consists of an oil tank, having a heater located in the bottom, and connections superheater which incloses the oil pipe leading to the burner, and leads to a connection with the tank 3. By means of suitable cooks the various steam passages may be controlled and the steam directed as required.

In the equipment oflocomotives for burning heavy fuel oil, it is necessary to maintain a sufficiently high temperature to insure a free flow of the oil and also to provide means for blowing out accumulations in the pipes and passages to insure satisfactory operation of the apparatus. By means of a pipe 14 steam is first admitted directly into the heating box containing the oil until the oil is raised to atemperature of approximately 180. This pipe maythen be closed and the coil pipe at the bottomof the tank is supplied with steam through the ipe 13, and these steam pipes arecontrolled y suitable cocks so as to maintain the proper temperature'.

Before starting the fire, the oil pipe 10, leading from the tank to the burner, should be cleansed of cold oil and accumulations, and this is done by opening the valve 15 which admits steam into the rear end of the pipe 10, thus blowing accumulations back into, the tank and cleansing the pipe. A drain cock 15 is provided-for releasing the waters of condensation from the superheater casing 11. A cook 16 is then opened,l'admit-' the burner proper, thus cleaning it out in readiness for service; Everything being thus in readiness, oil from the tank is admitted to flow through the pipe 10 into the receiver 17 from Which it may passinto the oil passage of the burner while steam is admitted from the pipe 1) into the steam passage of the burner to mingle with the oil in combustion Within the fire-box. The coil in the oiltank is freed from water which may condense in it, by meansof a pipe 18 with a controlling cook 19.

It is to be particularly noted that the heating box'3 which is located within the main fuel tank 3 and communicates therewith through the'valved passage 20, houses the heating coil 5 and also has the steam pipe 14 discharging directly therein. In starting up ting a jet of steam intov the oil passage of l heated during'the initial stages. 'Ihis preliminary heating is expeditiously effected by opening pipe 14: to discharge steam directly into the heating box, the steam thoroughly fuel tank for supplying oil thereto, of a heating box within the tank, a pipe connectlon between the heatm'g box and the burner, means formlng a communication between the heating box and the main fuel tank,

valve means within the box to control the passagesof said first means and pipe, and

means for heating the oil contained in the heating box before it enters'the, pipe whlch delivers theoil to the burner.

2. An oil burning apparatus comprising an oil tank, a burner, a pipe connecting the tank and burner, a superheater for the pipe arranged adjacent the burner, and fluid pressure means connected to the pipe between the burner andsuperheater for cleaning the pipe by blowing the oil in the pipe back through the super eater into the tank.

3. An oil burning apparatus comprising an oil tank, a heating box arranged therein and communicating through its bottom therewith to receive oil therefrom, a burner connected to the heating box, and heating means arranged adjacent the bottom of the box and about its inlet.

4. The combination in an oil burning apparatus', of a burner, an oil supply main with an inclosing steam super-heater, a

steam receiver connected with the main, and pipes leading from the receiver to the burner and to the rear ofthe oil main, an oil tank connected with the main, and direct and indirect heating means connected With the tank and operable independently of one another.

5. In an oil burning apparatus of the character described, a burner, an oil and a steam supply connected with .theburner, an oil tank having a coil in the bottom, 'a pipe leading directly into the body of oilin the tank, an oil main contiguous to theburner,

a controlling valve in the tank, a steam super-heater surrounding the oil main, a fountain head upon the, steam boiler, and valve-controlled ipes leading from said fountain to the urner, the super-heater, the rear of the oil main and to the direct and indirect. heaters Within the tank.-

6. An oil burning apparatus including an oil tank, means to apply steam heat directly and indirectly to the tank contents, a burner consisting of superposed oil and steam passages discharging into the boiler. fire-box, an

-oil main between the oil. tank and the burner, a superheater surrounding the main, pipes connecting the boiler with the tank heating devices with the superheater and with the burner, and means connecting the superheater with the rear of the oil main and with the oil passage of the burner.

7. An oil burning apparatus including a burner having steam and oil conduits, an 911 supp-1y tank, an oil supplymain connectlng the burner to the tank," a superheater inclosing the main, a steam manifold, a pipe leading from the latter to the burner, a sectherewith to receive oil therefrom,a burner connected to the heating box, a steam heating coil arranged Within the heating box and along its bottom tov maintain the oil therein at a flowing temperature, and a steam pipe discharging-into the heating box adjacent its bottom to preliminarily heat the oil therein. In testimony whereof I have hereunto set my hand inthe presence of two subscribing witnesses.
